How does boiling a solid substance affect its pressure?
Boiling a solid substance directly does not affect its pressure. However, when a solid substance boils and turns into a gas, the pressure can increase due to the expansion of the gas molecules.
A substance will exist as a gas at ambient temperature and pressure?
A substance will exist as a gas at ambient temperature and pressure if its boiling point is below the ambient temperature and its vapor pressure exceeds the atmospheric pressure at that temperature.
What is the difference in pressure between a gas at 720mm and a gas at standard pressure?
Standard pressure is 760mm Hg, so the difference in pressure is 40mm Hg (760mm - 720mm).
What gas has approximately the same density as carbon dioxide gas at standard temperature pressure?
Sulfur hexafluoride gas has an approximate density similar to that of carbon dioxide gas at standard temperature and pressure.
What is The only item that exists on the planet in all three states of matter at standard pressure?
water can be a liquid that turns into a solid, or a liquid that turns into gas.
When does enthalpy become zero?
Enthalpy can be zero for a pure substance at its standard state, where it is defined as the enthalpy of formation. This typically occurs at a reference temperature and pressure specified for the substance.
Is Flourine a gas or vapourl?
"Flourine" is a misspelling of fluorine, a chemical element that is a gas at standard temperature and pressure. The term "vapor" is usually restricted to a substance in the gas phase in equilibrium with a liquid that contains the liquid phase of the same substance. By this definition, fluorine could be a vapor only at a temperature far below standard temperature and pressure.
What does water change to when above 100 degrees Celsius?
After 100 0C at standard pressure water become a gas.
How does boiling a solid substance affect its pressure?
Boiling a solid substance directly does not affect its pressure. However, when a solid substance boils and turns into a gas, the pressure can increase due to the expansion of the gas molecules.
What is a substance's critical point?
A substance's critical point is the temperature and pressure at which the gas and liquid phases of the substance become indistinguishable, forming a supercritical fluid. At the critical point, the substance exhibits unique properties, such as density and viscosity, that differ from those of its gas or liquid phases.
A substance will exist as a gas at ambient temperature and pressure?
A substance will exist as a gas at ambient temperature and pressure if its boiling point is below the ambient temperature and its vapor pressure exceeds the atmospheric pressure at that temperature.
Is oxygen a sold liquid or a gas?
A gas at standard pressure
What state of matter is hydrogen?
Elemental hydrogen is a gas at normal environmental temperatures. At extremely low temperatures or extremely high pressure, it can become a liquid and even a solid.
What is the difference in pressure between a gas at 720mm and a gas at standard pressure?
Standard pressure is 760mm Hg, so the difference in pressure is 40mm Hg (760mm - 720mm).
What gas has approximately the same density as carbon dioxide gas at standard temperature pressure?
Sulfur hexafluoride gas has an approximate density similar to that of carbon dioxide gas at standard temperature and pressure.
What is the pressure of gas at ATP?
The pressure of gas has nothing to with ATP. However, the pressure of gas at STP, or Standard Temperature Pressure is 0 degrees Celsius and pressure is 1 ATM.
Which phase of a substance can exist when the pressure is less than the pressure of the triple point?
When the pressure is less than the pressure of the triple point, the substance can exist in the gas phase. At pressures below the triple point, the substance would typically be in the gas phase due to the lower pressure preventing the substance from forming a liquid or solid.
